Yeah just fret the string at first and last frets and measure clearance at the 9th fret. Just enough for at least a business card to fit under. Adjust to taste and the frets will tell you if you need more or less relief to keep it buzz free. As dark storm said problem frets that buzz will require pro attention to get action as low as possible if that's what you want.
